Is bottled water or filtered water better?
While much bottled water is of good quality, there are little or no regulations or means of ensuring bottled water quality… it is a self-policed industry for the most part. In contrast, the home water treatment industry is very heavily regulated. Manufacturers must do extensive testing and reporting to prove their products effectiveness at providing quality water. Manufacturers are required to supply “Performance Data Sheets” demonstrating the products ability to remove certain contaminants; bottled water companies are not required to demonstrate their waters quality.
